I'm trying to move the forums to php 8.0 - I'm getting a 500 error which I asked the hosting company to look into and this is their response. 

Any ideas?

The error we saw for the forums site when PHP 8.0 was implemented looks to have been related to the following script: /public_html/forums/init.php

[06-Jan-2022 15:04:05 UTC] PHP Fatal error: Declaration of IPS\hook28::link($warningRef = null, $groupFormatting = false) must be compatible with IPS\_Member::link($warningRef = null, $groupFormatting = null, $anonymous = false) in /home/dzxzyz/public_html/forums/init.php(903) : eval()'d code on line 5]

This is stating that the way that some items in the init script are being referenced is incorrect and would have to be altered

That’s an issue with a 3rd party app/plugin. 

@Daniel F remind me (others) again - PHP8 isn't officially supported for Invision Community yet right?

Yes, PHP 8.0.x is. it is PHP 8.1 that isn't officially supported yet.

Im running a forum on PHP 8.1.1 and no problems found (yet)
